DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

While the invention may be susceptible to embodiment in different forms,there is shown in the drawings, and herein will be described in detail,a specific embodiment with the understanding that the present disclosureis to be considered an exemplification of the principles of theinvention, and is not intended to limit the invention to that asillustrated and described herein.

Referring to FIG. 1 and FIG. 2, a zero insertion force (“ZIF”)electrical connector 100 of the present invention (short for electricalconnector) comprises an insulative housing 5 consisted of a cover 1 anda base 2, a drive means 3, a plurality of conductive terminals and aslider 4.

Referring to FIG. 2, in this embodiment, the base 2 comprises a frontend 201, a rear end 202, a left end 203, a right end 204, a top face 205and a bottom face 206. The front end 201 and the rear end 202 define aterminal-receiving area 20 therebetween. The terminal-receiving area 20defines a plurality of terminal-receiving cavities 21 through the topface 205 and the bottom face 206 arraying therein. Eachterminal-receiving cavity 21 receives a conductive terminal (not shown).The front end 201 and rear end 202 of the base 2 define a firstdirection (the cover 1 moving direction, said as follow) therebetween.Convenient for illuminating, the base 2 defines a fictitious X-axis andY-axis, and the first direction is Y-axis direction. The base 2respectively defines a cuneal portion 22 interval at the left and theright side thereof. In this embodiment, the left and the right side ofthe base 2 respectively defines two cuneal portions 22 (referring toFIG. 2). Referring to FIG. 4, the rear end 202 of the base 2respectively defines a post 23 at the left and the right side thereof toprevent the cover 1 and the base 2 relatively excessively backwardsdisplacing.

The base 2 defines a recess portion 24 downward depressed from the topface 205 of the base 2 and between the rear boundary of theterminal-receiving area 20 and the rear end 202. The recess portion 24is substantially toward a second direction slant with the firstdirection. In this embodiment, the recess portion 24 is slant from thetop left to the bottom right and has a first slant recess 241, a secondslant recess 242 and a transverse recess 243 connecting with two slantrecesses 241, 242. The slope of the first slant recess 241 and thesecond slant recess 242 is all same with the second direction. Thetransverse recess 243 is defined along the X-axis and the first slantrecess 241 is at the top left thereof and the second slant recess 242 isat the bottom right thereof The transverse recess 243 is defined betweentwo slant recesses 241, 242 and connecting with two slant recesses 241,242.

The rear end 202 of the base 2 extends a receiving base 25 rearward thatdefines an elongate groove 251 paralleled to the X-axis. The receivingbase 25 connects with the transverse recess 243 of the recess portion 24through a securing slot 26 paralleled to the Y-axis. The securing slot26 extends forward from the elongate groove 251 of the receiving base 25along the Y-axis and is through the transverse recess 243 of the recessportion 24 and into the top face 205 of the base 2, its function said asfollow.

The recess portion 24 receives a slider 4. In this embodiment, theslider 4 has a body similar with the recess portion 24. The slider has afirst body 41, a second body 42 and a transverse body 43 connecting withthe first body 41 and the second body 42. The first body 41 is receivedin the first slant recess 241, the second body 42 is received in thesecond slant recess 242 and the transverse body 43 is received in thetransverse recess 243. The parts of the body (the first body, the secondbody and the transverse body) 41, 42, 43 are shorter than correspondingrecess (the first slant recess, the second slant recess and thetransverse recess) 241, 242, 243. Therefore, the slider 4 can move alongthe second direction slant with the first direction in the recessportion 24.

Referring to FIG. 2 and FIG. 3, the slider 4 has a top surface 401 and abottom surface 402. The top surface 401 distant defines three ellipticprotrusions 44 paralleled to the X-axis. In this embodiment, threeelliptic protrusions 44 are respectively formed on the first body 41,the second body 42 and the transverse body 43. The elliptic protrusion44 has a long axis and a front surface 444 of the long axis isparalleled to the X-axis. The function of the elliptic protrusion 44 andthe front surface 444 will be illuminated as follow. The bottom surface402 of the transverse body 43 depresses a U-shaped groove 45 along ashort axis thereof and defines two securing holes 46 at each side of theU-shaped groove 45 for fastening a wearable member 47. The wearablemember 47 is U-shaped and made of metal and received in the U-shapedgroove 45 of the bottom surface 402 of the transverse body 43. TwoU-shaped sidewalls (not labeled) of the wearable member 47 respectivelyintegrated extend a pair of securing legs 471 corresponding to thesecuring holes 46. When the wearable member 47 is received in theU-shaped groove 45, the securing legs 471 corresponding insert into thesecuring holes 46 so as to make the wearable member 47 fasten in theU-shaped groove 45.

The base 2 defines a plurality of orientating holes 27 through the topface 205 and the bottom face 206 out of the terminal-receiving area 20.In this embodiment, the orientating hole 27 is rectangle. Some of theorientating holes 27 are defined between the rear boundary of theterminal-receiving area 20 and the rear end 202. Some of the orientatingholes 27 are defined between the front boundary of theterminal-receiving area 20 and the front end 201. A block 271 istransverse defined in each orientating hole 27 and not close theorientating hole 27.

Referring to FIG. 2, a drive means 3, preferably made of metal,comprises an operating portion and a cam member. In this embodiment, thedrive means 3 is a L-shaped pole and the operating portion is a firstarm 31 and the cam portion is a second arm 32 having a cam member 321.

Referring to FIG. 4, the second arm 32 of the drive means 3 is put inthe securing slot 26, the cam member 321 is in the transverse recess 243and free end of the second arm 32 extends into the base 2. After that,the slider 4 assembled with the wearable member 47 in the U-shapedgroove 45 thereof is put in the recess portion 24 and the cam member 321of the drive means 3 is in the U-shaped wearable member 47 so thathowever the cam member 321 of the drive means 3 turn will not fray theslider 4.The second arm 32 of the drive means 3 is put in the securingslot 26 and the first arm 31 of the drive means 3 is in the receivingbase 25 of the rear end 202 of the base 2. The first arm 31 pivots fromthe left to the right and reverse (referring to FIG. 7 and FIG. 8). Inthis embodiment, when the first arm 31 pivots to the right, part of thefirst arm 31 is received in the elongate groove 251 paralleled to theX-axis so that the first arm 31 supports the rear end 202 of the base 2(referring to FIG. 8).

Referring FIG. 1, FIG. 5 and FIG. 6, the cover 1 is slideably assembledonto the base 2 along the first direction and comprises a front end 101,a rear end 102, a left end 103, a right end 104, a top face 105 and abottom face 106. The cover 1 defines a pin-receiving area 10corresponding to the terminal-receiving area 20 of the base 2. Theterminal-receiving area 10 defines a plurality of through holes 11through the top face 105 and the bottom face 106 arraying thereincorresponding to the terminal-receiving cavities 21. A pin of a centralprocessing unit (“CPU”) (not shown) respectively inserts in the throughholes 11 and extends in the corresponding terminal-receiving cavity 21of the base 2.

The left end 103 and the right end 104 of the cover 1 respectivelyextend downward a vertical portion 12 and each vertical portion 12defines two receiving grooves 121 at inside thereof corresponding to thecuneal portions 22 of the base 2. The receiving groove 121 is longerthan the cuneal portion 22. When the cover 1 and the base 2 areassembled to an insulative housing 5, the cuneal portion 22 of the base2 is locked in the receiving groove 121 of the cover 1 to prevent thecover 1 breaking away from the base 2. And because the receiving groove121 is longer than the cuneal portion 22, sliding of the cover 1 is notaffected.

The bottom face 106 of the cover 1 respectively downward defines anorientating peg 13 corresponding to the orientating hole 27 of the base2 between the rear boundary of the terminal-receiving area 10 and therear end 102, and between the front boundary of the terminal-receivingarea 10 and the front end 101. Free end of the orientating peg 13 is ahook 131. When the cover 1 and the base 2 are assembled to theinsulative housing 5, each orientating peg 13 is received in thecorresponding orientating hole 27 and each hook 131 of the orientatingpeg 13 lock the block 271 of the orientating hole 27 so as to enhancethe cover 1 and the base 2 assembling. And because the long direction ofthe orientating hole 27 is parallel with the first direction and haveenough space to let the orientating peg 13 move therein, sliding of thecover 1 is not affected.

The cover 1 respectively defines an elliptic elongated hole 14 betweenthe rear boundary of the terminal-receiving area 10 and the rear end 102corresponding to the elliptic protrusion 44 of the slider 4. Thedirection of the long axis of the elliptic elongated hole 14 is the samewith that of the elliptic protrusion 44. When the cover 1 and the base 2are assembled to the insulative housing 5, each elliptic protrusion 44protrudes the corresponding elliptic elongated hole 14 and fastens withthe elongated hole 14 in the first direction. The front surface 444 ofthe elliptic protrusions 44 clings to the front wall of the ellipticelongated hole 14 and the elliptic elongated hole 14 is longer than theelliptic protrusion 44 in X-axis direction. Therefore when the slider 4displaces, the elliptic protrusion 44 protrudes the correspondingelliptic elongated hole 14 and engages with the elliptic elongated hole14 in the first direction so as to drive the cover 1 to displace.

In assembly, first, the second arm 32 of the drive means 3 is put in thesecuring slot 26 of the base 2, the cam member 321 is in the transverserecess 243 and free end of the second arm 32 extends into the base 2.After that, the slider 4 assembled with the wearable member 47 in theU-shaped groove 45 thereof is put in the recess portion 24 and the cammember 321 of the drive means 3 is in the U-shaped wearable member 47,and then, the cover 1 engages the base 2. The first arm 31 of the drivemeans 3 is in the receiving base 25 of the rear end 202 of the base 2and pivots from the left to the right and reverse. When the first arm 31pivots to the right, part of the first arm 31 is received in theelongate groove 251 so that the first arm 31 supports the rear end 202of the base 2. When the cover 1 engages the base 2, the receivinggrooves 121 of left and right vertical portions 12 of the cover 1 lockthe corresponding cuneal portion 22 of the base 2 to prevent the cover 1breaking away from the base 2. Each orientating peg 13 of the cover 1 isreceived in the corresponding orientating hole 27 and each hook 131 ofthe orientating peg 13 locks the block 271 of the orientating hole 27 soas to enhance the cover 1 and the base 2 assembling and not affect thecover 1 moving. The posts 23 at the left and the right side of the rearend 202 of the base 2 prevent the cover 1 relatively excessivelybackwards displacing. When the cover 1 and the base 2 are assembled tothe insulative housing 5, each elliptic protrusion 44 of the base 2protrudes the corresponding elliptic elongated hole 14 of the cover 1and fastens with the elongated hole 14 in the first direction. Thereforewhen the slider 4 displaces, the elliptic protrusion 44 protrudes thecorresponding elliptic elongated hole 14 and engages with the ellipticelongated hole 14 in the first direction so that the front surface 444can drive the cover 1 to displace.

When a CPU (not shown) is placed on the cover 1, pins of the CPUrespectively inserts in the through holes 11 and extends in thecorresponding terminal-receiving cavity 21 of the base 2. The pin of theCPU does not contact with a conductive terminal (not shown) received inthe terminal-receiving cavity 21 of the base 2 so it does no need aforce that the CPU is assembled onto the cover 1 of the ZIF electricalconnector 1. It is the reason of “ZIF”. The drive means 3 pivots to makethe cover 1 displace relatively to the base 2 along the first directionso that the pins of the CPU contact with the conductive terminalreceived in the terminal-receiving cavity 21 of the base 2.

Referring to FIG. 7 and FIG. 8, after the drive means 3 and the slider 4assembled with the wearable member 47 are located in the base 2, whenthe first arm 31 of the drive means 3 pivot to the left, the slider 4 isat the top left of the recess portion 24 (referring to FIG. 7); when thefirst arm 31 of the drive means 3 pivots from the left to the right, theslider 4 slant displaces from the top left to the bottom right of therecess portion 24 (referring to FIG. 8). After the cover 1 engages thebase 2, it will be illuminated how the cover 1 relatively displace tothe base 2 along the first direction through FIGS. 9-1 to 94 and FIGS.10-1 to 10-4. FIG. 9-1 shows the cover 1 at the first position. When thefirst arm 31 of the drive means 3 pivots to the left, the slider 4 is atthe top left of the recess portion 24 (referring to FIG. 7), the CPU(not shown) is placed on the cover 1, pins of the CPU respectivelyinserts in the through holes 11 and extends in the correspondingterminal-receiving cavity 21 of the base 2. The pin of the CPU does notcontact with a conductive terminal received in the terminal-receivingcavity 21 of the base 2; FIGS. 9-2 to 9-4 respectively shows the cover 1does not displace to the base 2. FIG. 10-1 shows the cover 1 at thesecond position and the first arm 31 of the drive means 3 pivots fromthe left to the right. Because the recess portion 24 is thicker than theslider 4 in Z-axis direction, the cover 1 will not press the slider 4and let the slider 4 not move. When the drive means 3 pivots, the cammember 321 turns following the drive means 3 and pushes up the slider 4.Though the slider 4 is pushed up to the culmination, the slider 4 stillcan displace. The slider 4 only can displace along the recess portion 24from the top left to the bottom right because the slider 4 is coveredwith the cover 1 and limited by the slant recess portion 24 between leftand right. When the slider 4 displaces, the elliptic protrusion 44protruding the corresponding elliptic elongated hole 14 also displace inY-axis direction. The front surface 444 of the elliptic protrusion 44drives the cover 1 to displace forward along the first direction so thatthe CPU assembled on the cover 1 synchronously move forward and pins(not shown) of the CPU contact with the conductive terminal (not shown)received in the terminal-receiving cavity 21 of the base 2. FIGS. 10-2to 10-4 respectively shows the cover 1 forward displace to the base 2.

When the cover 1 moves from the second position back to the firstposition, the first arm 31 of the drive means 3 pivots from the right tothe left and the slider 4 displace along the recess portion 24 from thebottom right to the top left. When the slider 4 displaces, the ellipticprotrusion 44 protruding the corresponding elliptic elongated hole 14also displaces in Y-axis direction so as to drive the cover 1 todisplace rearward along the first direction. The CPU assembled on thecover 1 synchronously move rearward and pins (not shown) of the CPU donot contact with the conductive terminal (not shown) received in theterminal-receiving cavity 21 of the base 2.

In the above embodiment, the recess portion 24 comprises the first slantrecess 241, the second slant recess 242 and the transverse recess 243connecting with two slant recesses 241, 242. But, the recess portion 24also can be designed a slant recess pointing to the second direction andno transverse recess 243. The slider 4 also can be designed in the sameway to engage the recess portion 24.

The CPU has many pins and if each pin does not accurately contact withthe conductive terminal, the CPU can not work. Therefore, it is veryimportant to make the displacement of each part of the cover 1accordant. Illuminated as above, the elliptic protrusions 44 andelliptic elongated hole 14 of the ZIF electrical connector 100 of thepresent invention are all paralleled to the X-axis direction (verticalto the first direction). The surface making the elliptic protrusions 44forward and vertical to the first direction will make the front surface444 of the elliptic protrusion 44 entirely connect with the cover 1.When driving the cover 1 to displace forward along the first direction,the whole front surface of the elliptic protrusion 44 drives the cover1. Because the forward direction driving is assured, each part of thecover 1 displaces accordant so as to enhance each pin of the CPUaccurately to contact with the conductive terminal. The drive means ofthe ZIF electrical connector of the present invention is defined on oneside of the insulative housing crossing the first direction whichaccords with new specification brought by IC manufacturer. The drivemeans of the ZIF electrical connector of the present inventionindirectly drive the cover of the ZIF electrical connector and make thecover displacement, and the slider moves along a direction slant withthe moving direction of the cover, all the above are different from theprior art.
